Storyboard Text

  • David is a professional trap shooter. He knows that the best time to shoot is when the disk is 10 ft in the air and 20 ft away from him. He is curious about what his angle of elevation is from the ground. so he uses trig.  he calculates that sin-1  = 10/20. so the angle is 30o

  • 20 ft
  • 10ft
  • OH NO! His clay thrower is malfunctioning!
  • Good news! He fixed the thrower! But it isn't trowing the clay at the same angle anymore. The clay is only reaching 5 ft from the thrower when it is 10 ft off the ground. He wants to know the new angle, so he calculates that tan-1 = 10/5. He finds that the angle is 63.4o

  • 5ft
  • 10ft
  • Now David wants to know when it is best to shoot the target with the new angle.  He now calculates that Cos(63.4) = 10/x. which equals 22.3
  • 63.4o

  • 5ft
  • 10ft
  • Now David is hitting his shots. All thanks to Trig!
